BASED UPON ICC ES EVALUATION
Attn: Dave Jablonski REPORT NO. ESR-1799
(800) 848-5611
REEVALUATION DUE
DATE: September 1, 2018
Issued Date: May 1, 2017
Code: 2014 LABC
GENERAL APPROVAL – Reevaluation - Ramset Power-Driven Fasteners
DETAILS
When in compliance with the use, description, design, installation, conditions of use, and
identification of Evaluation Report No.1799, reissued June 2016, by the ICC-ES Evaluation
Services, Incorporated, the report, in its entirety, is attached and made part of this general
approval.
The parts of Report No.ESR-1799 which are excluded on the attached copy have been removed
by the Los Angeles City Building Department as not being included in this approval.
The approval is subject to the following conditions:
1. The fasteners shall not be used to resist seismic loads, except when used with
architectural, electrical and mechanical components as described in Section 13.1.4 of
ASCE 7-10, and as follows:
a) Concrete base materials: The ITW Ramset fasteners installed in concrete base
materials may be used to support acoustical tile or lay-in panel suspended ceiling
systems, distributed systems and distribution systems where the service load on any
individual fastener does not exceed the lesser of 90 lbf or the published allowable load
shown in Tables 1, 2, 5, and 6 of the attached ICC-ES ESR-1799 evaluation report, as
applicable.

b) Steel base materials: The ITW Ramset fasteners installed in steel may be used where
the service load on any individual fastener does not exceed the lesser of 250 lbf or the
published allowable load shown in Table 3 and 4 of the attached ICC-ES ESR-1799
evaluation report, as applicable..
c) For interior, nonstructural walls that are not subject to sustained tension loads and are
not a bracing application, the ITW Ramset power-driven fasteners may be used to
attach steel track to concrete or steel in all Seismic Design Categories. In Seismic
Design Categories D, E and F, the allowable shear load due to transverse pressure
shall be no more than 90 pounds when attaching to concrete; or 250 pounds when
attaching to steel. Substantiating calculations shall be submitted addressing the
fastener- to-base-material capacity and the fastener-to attached-material capacity.
Interior nonstructural walls are limited to locations where bearing walls, shear walls or
braced walls are not required by the approved plans. The design load on the fastener
must not exceed the allowable load shown in Tables 1 through 4 of the attached ICC-
ES evaluation report, as applicable. The design load on the fastener must not exceed
the allowable load shown in Tables 1 through 4 of the attached ICC-ES ESR-1799
evaluation report, as applicable.
2. Shear values for fasteners in concrete are for connections of steel to concrete. Allowable
bearing stresses for the steel material being connected shall not be exceeded.
3. The minimum concrete thickness shall be three times the fasteners embedment in concrete,
except where noted otherwise in this report.
4. For working values in steel, the fasteners shall have sufficient length so that the entire pointed
portion of the shank pierces the steel plate, except where noted otherwise in the tables of the
attached evaluation report.
5. The allowable values listed in the attached report and tables are for the fasteners only.
Connected members shall be checked for their capacity (which may govern).
6. Use of the low velocity fasteners to the metal deck, the fasteners shall be installed through
the metal deck and into the concrete at the upper or lower flute as designated in the table.
The fastener must be a minimum of 1 1/8 inches from the edge of the deck web and 4 inches
from the end of the deck. The minimum fastener spacing is 4 inches.
7. No increase is permitted in the tabulated allowable load values for short duration loading.
8. The fasteners shall be installed per the manufacturer's instructions, a copy of which shall be
available at each job site.
ITW Ramset

9. The containers of the fasteners shall be labeled with the ITW Ramset company name, the
fastener product name, length, catalog number, and quantity, the evaluation report number
(ESR-1799); and the manufacturing date and lot number. In addition, all of the fasteners,
except the 1600 W series fasteners, shall be identified by the letter “R” stamped into the fastener head.
DISCUSSION
The report is in compliance with the 2014 Los Angeles City Building Code.
The approval is based on tests in accordance with ICC-ES Acceptance Criteria for Fasteners
Power-driven in to Concrete, Steel and Masonry Elements (AC70), dated October 2006.
This general approval will remain effective provided the Evaluation Report is maintained valid
and unrevised with the issuing organization. Any revisions to the report must be submitted to this
Department for review with appropriate fee to continue the approval of the revised report.
Addressee to whom this Research Report is issued is responsible for providing copies of it,
complete with any attachments indicated, to architects, engineers and builders using items
approved herein in design or construction which must be approved by Department of Building and
Safety Engineers and Inspectors.
This general approval of an equivalent alternate to the Code is only valid where an engineer and/or
inspector of this Department has determined that all conditions of this Approval have been met in
the project in which it is to be used.
